Give Corbyn a shot at a general election: if he loses, then he will step down. Trying to undermine him from the inside before that point is nothing but a massive favor to the Tories. Labour should have called for a general election right after Brexit, but were instead distracted by an internal, and now failed, attempt to unseat Corbyn.
Also, the left needs to be left: a middle of the road, neoliberal opposition is no opposition at all, and Ed Miliband learned that the hard way.
